摘要: A method of detecting variation in the diameter an optical fiber includes following steps: transversely illuminating a portion by means incident light beam, measuring radiation pattern produced predetermined acute angular sector around fiber, and causing modification this way. The is defined angles 90° 105° or 255° 270°.
